Help Low on Space, "System data" huge!

Hi! I'm a relative Android newbee, had MyTouch 4g for two months.

I'm having problems with the "Low on space" warning. I have moved all my apps to the SD card which helped for a while but the warning came back. I then started clearing out data, uninstalling apps but days later it still came back. I read about the "diskusage" app and have it installed after clearing more data. What it is telling me is of my total data (1162 MiB) 115 MiB is free, 63.3 MiB is Applications and 983 MiB is "System data". There is no way for me to tell what this system data is made up of. I installed diskusage on my wife's MyTouch 4G and found her system data was only a little over 100 MiB.

How can I clean up the system data so I get my phone back to normal?

Thanks!
 
Do you do a lot of web surfing? If so, you should try to wipe cache and history from the browser. Also, if you do a lot, get Dolphin Browser HD (free) and set it to cache to the SD card.

This is the most likely culprit. It was for me a while back on the Nexus One.

I'm not a big web serfer, but yes, I have cleared cache and history from the browsers. I used to have Dolphin installed but removed it to try to get my size down.

983 MiB seems just HUGE! It would take lots and lots of apps to use that much space! I'm wondering if it were some kind of memory leak. I don't understand why it doesn't go away when I reboot.

Arg! And it is getting worse. I uninstalled Firefox and then did a rescan in diskusage and since this morning my "System data" has gone UP to 1022 MiB from 983 MiB. That is another 39 MiB, for those of you keeping score at home. I'm not doing anything with the phone either other than rebooting, running diskusage and uninstalling Firefox.

check you email settings and attachment download settings. i'd also take a gander at your data usage trends. i wonder if an app is constantly downloading something onto your system.
if your OS is stock and you haven't rooted/modified it, you shouldnt be experiencing memory leaks. even with memory leaks you often regain the space after a reboot.
do some more investigating. but it sounds like you should prepare to start from scratch again anyways (even after finding the cause).

Thanks all. I thought about the email attachments potential, but I don't get many (if any) of those. I never have rooted the phone and it is the stock OS. It is odd that restarting was not clearing out the problem. That "System data" was only growing, never getting smaller.

I realized I had run out of options so last night I did a factory reset. I was actually surprised how quickly I was up and running again. Any apps I had not uninstalled that were on my SD were still there, of course. Before resetting I saved my contacts to SD so they were there too. Actually, I think it pulled them from Google because I didn't do the "restore from SD". Other than the apps I deleted myself and saved data on games, I think I'm no worse for wear. I'm now running with over a 1000 MB free.

As suggested, I will monitor this now. If I run into it again, at least I know the factory reset isn't the end of the world.

Thanks everyone for their help! :D

With the strides that Google has been making with the market, saving info and all that, resets are not that bad nowadays.I came from running an HD2 Modded with a MyTouch4G stock ROM to the actual MyTouch 3G phone and once I logged into my google account, all kinds of magic happened, even resetting my wallpapers back.

It's a nice thing. :D

Glad to hear it's worked so far. I actually left android for a while and when i got this phone most of my old apps and all of my calendar/contacts that i always sync with google automatically popped up after about an hour of activation. I think my first day of data use was 50mb just for synchronizing all accounts and stuff...haha.
The only pain in wiping is re-doing some of the settings and arranging your home screen. Everything else should be quite simple or just require a username and password. :)

I thought I'd give you all an update. Here it is now June and I still have this ongoing problem. I may be unique because I don't find a lot of info regarding this problem on the web.

I monitor my memory usage using DiskUsage app. I have to rebuild the phone about every two weeks. If I catch the problem in progress, I can usually stop it from building by rebooting, but the memory usage is still stuck and eventually when it takes off again I run low on memory. I have tried a task manager/killer app with little success. Even if I kill all apps the memory leak continues.

I finally called T-mobile to see if they could help. After walking me through a whole diagnostic script she finally agreed to send me a new phone. Alas... two weeks later I was low on memory and needed to rebuild again. I stopped in a T-mobile store to explain my problem, but they were totally worthless. I knew a whole lot more than the girl there.

So I know the problem isn't the hardware.

Has to be an app going nuts. I want to rebuild from scratch without the apps being restored by my google account. I tried deleting the restore by going to Setting -> Privacy and unchecking the Backup My Setting which was supposed to delete the backup from my Google account. However, when I rebuild the phone it still automatically installed all my old apps. I don't want to have to create a new google account, but that may be my next best option.

Thanks for listening. If anyone has run into a similar problem please let me know.

The way I went about troubleshooting this was to use Disk Storage to find an area that was taking up a huge amount of space ("System data" in \data, as reported by DS), then I used Yaffs Explorer (my favorite so far; enable all the root options) to find and view that folder. I found about 20 or so "alog*" files, 15 of which were 8mb each and one "alog_events" that was 724mb. So I just deleted that, rebooted, and I am back in business, at least for now.

I ve got the Desire S and over 1GB of internal storage. I had quite some apps installed but not THAT many. After trying moving apps to SD, delting cache and data files I saw it was useless.
Using DiskUsage I found out that \data\system data took a huge amount of memory (this you can see also with an unrooted device, but not more).
My solution:
1) Root the device (plenty good guidelines of how to do it and it was less painful that expected)
(Comment: After this, I searched for files acc. nomonkeynodeal with yaffs explorer and ES Explorer, latter allowing also to delete single provider apps; however, it was not before restarting that I miraculously attained possibility for next step.)
2) Give root permissions (superuser) to DiskUsage and have a look into the \data\system data.
3) Here I found the folder com.android.htcprofile and inside that folder the file "anr_history.txt" which was 833 MB big
xdadevelopers show this is a file generated as "Application Not Responding". Deleting it gave me great pleasure and now I have loads of memory available. :p
This forum gave me the right hints - thanks!

Hi, Like Matroid I had this same issue and it was also with /data/data/com.android.htcprofile/anr_history.txt which had grown to a little over 650 Mb.. deleting it immediately fixed the problem tho you will need root to do this I suspect.

Not had a chance to see why log had ballooned - deleting it is like treating the symptom rather than the cause - but glad I don't have to a fresh install of Android just yet (though this might not be a bad idea at some point anyway!) (I'm using 2.3.3 on HTC Sensation XE)

Good luck everyone, hope it is as simple as that :)

Hello,

I had exactly the same problem with an unrooted Samsung Galaxy S2 running Android 4.1.2 (JellyBean). Storage space was growing by about 30MiB each day. Factory reset didn't help (it cleared the storage, but it still kept growing).

I started out from the principle that I didn't want to root my phone to fix this... that didn't work.

So finally I did the following:
  1. Rooted my phone
  2. Gave root rights to DiskUsage (you can do that in the app itself)
  3. Started scanning the different root folders one by one
  4. When scanning /data, I saw that /data/log/ was taking up around 400MiB
  5. There were a lot of .txt.tmp file with the same name in that folder (I forgot to note the name). I deleted all those files using the (downloaded) 'File Manager' app. Please note that I did not delete all files in /data/log. There were 21 small files with other names. Maybe deleting them is no problem, but I don't know enough about the operating system to be 100% sure, so I just left them.
  6. I now forced DiskUsage to do a new scan and system data was now only 30MiB, yay :). Watch out, if you don't force DiskUsage to do a new scan, it will still show the old scan (I just restarted my phone after I deleted all files).

Conclusion: I did not succeed in fixing this problem without rooting my phone. After I rooted my phone, I succeeded in less than 30 minutes. This is not how it should be! People should not have to root their phone to fix problems like this. Anyway, I consider myself to be a nerd now :).

I am having the same issue with a Galaxy S2 (vodafone) looked at the root cleaner app but it states it will only work on rooted devices which I do not want to do, I have had the phone now for two years and it has performed well until the JB updates, for some reason I received two JB updates, not sure what were the differences as it said it was version 4.1.2 on both occasions.
The space issue is becoming a real issue as any update to my apps over 7 or 8 MB fail due to 'insufficient space available' I have uninstalled loads of apps, moved all the apps that will move to SD to the SD card and still the space is decreasing, what the hell is going on!! sometimes I get a 'invalid file package' message which I have put down to insufficient space to store the downloaded file not completing.

I will monitor this thread in the hope that someone out there finds a solution before I go down the reset option which I am really loathed to do as it took ages to get the phone to look and work the way I wanted it to, apart from the low space issue of course!!

I just wanted to say thanks to everybody in this thread! I have the international unlocked Samsung S2 on 4.1.2 and was constantly getting the "Insufficient storage" errors. I rooted my phone (so easy!) and instead of having 200MB available, now I have almost 1GB from deleting all those logs mentioned above (insane!).

Really amazing how this stuff isn't cleared out automatically by Android or Samsung (whoever is responsible for writing the logs). ..I've been having issues the past week or two with my phone and I suspect it could be due to the low space remaining so hopefully this resolves it.

Thanks again!

I installed the free version of SD maid onto my rooted Samsung S2, located the data/log folder and deleted 5GB of log files from this folder - everything in it (there were a LOT of small ~1.4MB files).

My system data in the DiskUsage App has shrunk and my phone is working properly again :)

I didn't need to reinstall anything either!!
